  Purpose

The study will assess the regression of yellow plaque content of the lipid pool after aggressive lipid therapy by utilizing NIR spectroscopy. Statin therapy using Rosuvastatin 10-40 mg will be compared to the statin therapy of either Atorvastatin or Simvastatin. This is a single site study. A total of 100 subjects will randomized, of which 40 will receive intensive lipid therapy (Rosuvastatin 40mg) and 40 will receive standard care lipid lowering therapy.

Primary Outcome Measures:
  • Lipiscan - Lipid core burden (LCBI) [ Time Frame: at baseline and at 6-8 weeks after intervention ] [ Designated as safety issue: No ]
    The study will assess the regression of yellow plaque content from the atherosclerotic lipid pool after statin therapy by utilizing NIR spectroscopy as compared from baseline to 6-8 weeks after intervention.


Secondary Outcome Measures:
  • Fractional Flow Reserve (FFR) value [ Time Frame: at baseline and at 6-8 weeks after intervention ] [ Designated as safety issue: No ]
    Change in FFR as related to change in yellow plaque index as compared from baseline to 6-8 weeks after intervention.

  • intravascular ultrasound (IVUS) parameters [ Time Frame: at baseline and at 6-8 weeks after intervention ] [ Designated as safety issue: No ]
    Change in atheroma volume and lumen CSA on IVUS as related to change in yellow plaque index as compared from baseline to 6-8 weeks after intervention.

  • post PCI cardiac enzymes [ Time Frame: at 6-8 weeks after intervention ] [ Designated as safety issue: No ]
    Correlation of yellow plaque index with post procedure CK-MB, Troponin-I release.

  • Major Adverse Cardiac Events (MACE) [ Time Frame: at 6-8 weeks after intervention ] [ Designated as safety issue: No ]
    MACE defined as a combined clinical endpoint of death, MI (Q wave or non Q-wave with CK-MB >3 times above the upper normal limit (48 U/L), urgent revascularization or stroke at 30 days and 1 year.

  • blood chemistry - HsCRP [ Time Frame: at baseline and at 6-8 weeks after intervention ] [ Designated as safety issue: No ]
    Correlation of yellow plaque index with changes in levels of peripheral blood/serum leukocytes, leukocyte sub-types, HsCRP as compared from baseline to 6-8 weeks after intervention

Detailed Description:

Coronary artery disease (CHD) remains to be a leading cause of death in most countries (1) (2). It is well known that reducing cholesterol level by statin therapy is associated with significant reduction in plaque burden. REVERSAL (3) and ASTEROID (4) trials showed that in patients with coronary artery disease lipid-lowering with atorvastatin or rosuvastatin respectively reduced progression of coronary atherosclerosis and even cause repression of some lesions. CHD clinical events are related to plaque instability due to lipid content within the atherosclerotic plaque. High dose atorvastatin has shown to reduce the plaque lipid contents on serial IVUS analysis at 12 months. Therefore reduction in lipid content and thereby the plaque burden by lipid lowering therapy may stabilize the plaque and reduce cardiovascular events. High sensitivity C-reactive Protein (HsCRP) is an inflammatory biomarker that independently predicts future vascular events. In JUPITER (5) trial rosuvastatin (Crestor) significantly reduced the incidence of major cardiovascular events in apparently healthy people with elevated HsCRP. IVUS was utilized to demonstrate change in coronary artery vessel wall morphology over a relatively short period of time, but provided no data on the lipid content in the vessel wall. The application of NIR spectroscopy to identify lipid deposition within coronary arteries has been validated in ex vivo studies. Infrared spectra are collected as follows: Light of discrete wavelengths from a laser is directed onto the tissue sample via glass fibers. Light scattered from the samples is collected in fibers and launched into a spectrometer. The plot of signal intensity as a function of wavelength was used to develop chemometric models to discriminate lipid-cores from non-atherosclerotic tissue, and from atherosclerotic tissue that is predominantly fibrotic and from blood elements.

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Patient > 18 years of age and willing to participate
  • Stable patients who will undergo cardiac catheterization and PCI (intent to stent)
  • Patient is willing to go on a cholesterol lowering medication for the duration of the study and willing to change statin therapy to the randomized statin therapy regardless of previous statin therapy and dose (e.g. Atorvastatin 80 mg) Patients that are screened for this study and are receiving another Statin such as Pravachol will be required to be willing to change their therapy to Rosuvastatin as per is randomization. If patients are receiving another statin, such as pravachol, or any other agent, and are at appropriate Lipid levels, they will be permitted to continue this therapy (if randomized to the standard therapy arm). There are a virtually unlimited number of possible scenarios for potential combination of all Lipid lowering agents at the time of enrollment that patients may be taking.
